Using Ruggedized Test Equipment to Solve Jet Engine Problems

A jet engine is the very definition of “mission-critical.” A critical failure could cause a serious accident that endangers hundreds of lives. To prevent this from happening, manufacturers perform extensive testing on jet engine components, systems, and manufacturing processes.

Ruggedized Software Defined Radio Solutions

Pixus Technologies (Waterloo, Ontario) has developed ruggedized versions of commercial software defined radios. The RX310, the first in the series of small form factor ruggedized devices, utilizes the USRP software defined radios from Ettus Research, a National Instruments brand. The weatherproof enclosure features IP67 sealing for water and dust ingress. It is also designed for MIL-STD-810 for shock/vibration and MIL-STD-461 for EMI. The RX310 contains two extended bandwidth daughterboard slots covering 10 MHz – 6 GHz with up to 160 MHz of baseband bandwidth, dual 1/10 GigE high-speed interfaces, and a large user-programmable Kintex-7 FPGA. The unit is 302mm wide × 400mm long × 98mm tall with conduction-cooled fins for heat dissipation.

Modular Biosensor Patch

Researchers are identifying new biomarkers to help monitor cognition and stress in the human body and enhance human performance. Traditional biomarkers like heart rate, temperature, oxygen partial pressure, blood glucose, electrolyte concentration, and others have been correlated with cognition and stress states. However, the correlation is indirect. Molecular biomarkers with stronger and more specific links are preferred.

Hardware Design of a High Dynamic Range Radio Frequency (RF) Harmonic Measurement System

Radio frequency (RF) circuit elements that are traditionally considered to be linear frequently exhibit nonlinear properties that affect the intended operation of many other RF systems. Devices such as RF connectors, antennas, attenuators, resistors, and dissimilar metal junctions generate nonlinear distortion that degrades primary RF system performance. The communications industry is greatly affected by these unintended and unexpected nonlinear distortions. The high transmit power and tight channel spacing of the communication channel makes communications very susceptible to nonlinear distortion.

Eye Tracking Technology

Much debate surrounds the skills shortage burdening the manufacturing sector of aerospace and defense (A&D). Industry 4.0, the Baby Boomer retirement wave, and a lack of properly trained workers underpins this issue, and while it's widely acknowledged, there's no clearly defined way to address it.

Unique Method for Orifice Production

To produce accurate, repeatable orifices, all the variables that might influence the Cd Value (Coefficient of Discharge) must be controlled during production. This includes the orifice hole length, edges, surface finishes, roundness and the elimination of all tool marks, burrs, ragged edges and irregularities. If any one of these areas is not perfectly managed, the orifice flow rates will vary from piece to piece thereby making it impossible to predict flow with any accuracy.
